It provides the tsp-drones-core module to deal with instances and solution. The tsp-drones-heur module provides the heuristics discussed in the paper, and the tsp-drones-mip module provides the IP model discussed in the paper. Finally, the tsp-drones-generate module provides a command line utility that can be used to generate instances.
